Gentamicin and low dose piperacillin in febrile neutropenic patients

: One hundred and twenty-seven febrile neutropenic patients were randomized to receive empirical antibiotic therapy with intravenous gentamicin and 12 g/day or 8 g/day piperacillin. Despite a high incidence of Hickman catheter infections by antibiotic-resistant bacteria, there was an overall response in 56% of patients and no difference in the numbers responding to each antibiotic regimen. In addition, the duration of fever was not significantly different in the two groups of patients. The majority of the unresponsive patients responded to the addition of further antibiotics and there were only two infection related deaths. The results suggest that high dose antibiotics are not essential for the initial empirical therapy in febrile neutropenic patients.
